Ah good. I don't use XML::Twig, so I don't have a deep knowledge of it.
If it consistently ignored namespaces when map_xmlns isn't used, it would be a great shortcut despite being non-standard since there is rarely need to deal with namespace conflicts. (The module never claimed them to be a real XPaths.) Unfortunately, it doesn't consistently ignore namespaces.
On the plus side, it works according to standard when map_xmlns is used. (Well, I'm not sure how namespaces interact with attributes, so I'm simply commenting on elements.)
